Abstract
PURPOSE: To stop accurately at a desired position without giving shock to a rotation body by holding latch elasticly which shuts off power source at the same time with infixing into the recess of rotation body.
CONSTITUTION: Since the switch 33 of driving motor is closed at the same time with releasing latch 36 from the latch recess 31 when the electromagnet 40 is energized, the rotation body 30 is revolving in a counter-clockwise direction with the driving motor. Energizing time of electromagnet 40 is remarkably short, which is constrained by outer periphery of rotation body 30 to inhibit the reset of latch 36. When the rotation body 30 is rotated 180 degrees, the latch 36 is introduced into latch recess 32 by inertia force of spring 38 and simultaneously the switch 33 of driving motor is opened. The rotation body 30 is further revolving as extending the spring 38 by inertial force where pulling back by accumulated force of spring 38 after stopping rotation and stops by returning to the click point between return lock latch 41 and latch recess 31.
